To Enter Data with the Numeric Keypad
The synthesizer numeric keypad and units terminator keys provide one way
to enter function parameters.
1. Select the desired function key or shifted function key.
The function must have a numeric value (parameter) associated with
it in order to enter a new value with the numeric keypad. 4 5 and FREQ
4POWER LEVEL 5 are examples of functions with parameters.
For example, to select power level so that its parameter is active, press the
4POWER LEVEL 5 key.
Notice that a cursor ( 9 ) appears over one of the digits in the power level
display. The cursor will always appear over one of the digits of the active
parameter.
NOTE
Two cursors will appear ( 9 9 ) when the cursor is positioned o the display.
2. Enter the desired value of the parameter by pressing the numeric keys
and, if necessary, the negative and decimal keys.
Notice that, as you press the keys, the display shows the numbers that are
entered.
3. Press the appropriate units terminator key to enter the value.
The units terminator keys appear to the right side of the numeric keypad.
The following steps show how to enter a value of 09.5 dBm for power
level:
a. Press the 4 5 key.
POWER LEVEL
b. Press 40 5 on the numeric keypad.
9.5
c. Press the dBm (4 5) key to terminate the entry.
GHz
Once you terminate the entry, the synthesizer updates the power level
value to 09.5 dBm.
2-3
To Modify Data with the Knob
The knob on the synthesizer front panel is used to modify data. You turn the
knob in order to increase or decrease the parameter value of the currently
active function. Additionally, you can modify the position of the cursor ( 9 )
that is over the active parameter in order to increase or decrease the rate at
which the function parameter changes.
1. Select the function key of the parameter to be modi ed.
When the function key is selected, the cursor appears over one of the
digits of the selected parameter.
For example, to select the frequency function, press the 4
FREQ 5 key. The
frequency parameter is selected when the cursor appears over one of the
digits of the frequency display.
2. Turn the knob clockwise to increase the parameter or
counterclockwise to decrease the parameter.
When you turn the knob, the digit under the cursor increases or decreases
in steps of one.
For example, when frequency is in its preset state and is the active
parameter, the frequency display shows the following:
3.000000000 GHz
where the cursor appears over the third \0" to the right of the decimal.
When you turn the knob in this case, the output frequency changes in 1
MHz steps.
3. If you wish to move the position of the cursor one position to the right,
press the 4)5 key.
Pressing 4)5 once moves the position of the cursor to the right one digit in
order to decrease the knob resolution by a factor of ten.
4. If you wish to move the position of the cursor one position to the left,
press the 4(5 key.
4(5 moves the position of the cursor to the left one digit in order to
increase the knob resolution by a factor of ten.

5. Continue to press the 4)5 or 4(5 key until the cursor is positioned over
the desired digit.
For example, suppose that frequency is the current active parameter, and
you wish to change the cursor position from 1 MHz to 1 GHz. The steps
that follow illustrate how to accomplish this:
a. Press the 4 5 key.
PRESET
When the instrument has been set to the preset state, the frequency
display indicates the following:
3.000000000 GHz
where the cursor appears over the third \0" to the right of the decimal.
b. Press the 4(5 key three times. This moves the cursor from the position
corresponding to MHz to the position corresponding to GHz. (The
cursor is now over the \3".)
c. Rotate the knob slowly so that you can see the frequency change in 1
GHz steps.
NOTE
* + * +
The Knob and 4 5, 4 5 keys operate independently of each other. The 4 5, 4 5 keys increase or
decrease parameters in de ned steps.
2-5
To Modify Data with the Arrow Keys
The synthesizer 4*5 and 4+5 (arrow) keys increase or decrease the value of the
currently active parameter by an amount set with the 4 STEP SIZE 5 key. The
amount set with the 4 5 key is referred to as the increment value.
STEP SIZE
1. Select the function key of the parameter to be modi ed.
When the function key is selected, a cursor
( 9 ) appears over one of the digits of the selected parameter.
For example, to select the frequency function, press the 4
FREQ 5 key. The
frequency parameter is selected when the cursor appears over one of the
digits of the frequency display.
2. Press the 4*5 key to increase the parameter by the current increment
value or press the 4+5 key to decrease the parameter by the current
increment value.
For example, when frequency is in its preset state, the frequency display
shows the following:
3.000000000 GHz
where the cursor appears over the third \0" to the right of the decimal.
The preset frequency increment value is 100 MHz. When you press the 4*5
key, the value of frequency increases to 3.100000000 GHz.
3. If you wish to change the increment value, you can do so using the
4STEP 5
SIZE key.
The 4 STEP SIZE5 key allows you to change the increment value of the
currently active function. For example, suppose that frequency is the
current active parameter, and you wish to change the increment value
from its preset value of 100 MHz to 250 MHz. The steps that follow
illustrate how to accomplish this:
a. Press the 4 5 key.
STEP SIZE
b. Type 4 5 on the synthesizer numeric keypad.

If no cursor ( 9 ) appears over a parameter in the display:
Check that the ENTRY OFF function is not enabled.
The ENTRY OFF function is enabled when the cursor ( 9 ) doesn't appear
over any of the parameters in the display. To return to normal entry mode,
press the desired function key which has a numeric parameter associated
with it (for example, press 4 5 if you want to enter frequency).
FREQ
If the parameter you are trying to enter is not accepted by the
synthesizer:
Ensure that you are not trying to set the parameter greater than or less
than its limit. Refer to the speci cation table in this manual for the
parameter limits.
Check that the MSG LED annunciator is o.
If the synthesizer MSG annunciator is on, there is a problem with the
synthesizer. To determine the error and turn o the MSG annunciator,
refer to \To Read the Contents of the Error Queue" in this chapter and the
listing of error messages in Chapter 8.
If the synthesizer does not display/output the carrier frequency entered:
Check that the frequency multiplier value entered is the expected value.
When a multiplier value other than one is entered, the frequency
resolution of the signal before multiplication must be obeyed. For example,
for a desired frequency of 40 GHz using a multiplier value of three, the
synthesizer would have to output a frequency of 13.333333333 GHz. Since
frequency resolution at that frequency is 1 kHz, the closest the synthesizer
can set the frequency is 13.333333000 GHz. This yields 39.999999000 GHz
after multiplication, not 40 GHz.

Programming Problems
If the synthesizer does not respond to programming commands:
Refer to the procedure, \To Set the HP-IB Address," in this chapter to check
and, if necessary, change the HP-IB address.
